touch screen capacitive works by the capacitance differential between the screen and your finger wherever there is difference in capacitance on the screen is where you are touching and the screen knows what function you are trying to do depending on what is displayed on the screen.
No. It have resistive touch screen.
Nope..!! It has a Resistive Touch Screen..!!
The thin layer technology of the capacitive touch screen allows for a sharper picture than other touch screens. Also, since the capacitive touch screen is responsive to human touch but not most other objects, accidental touches are less of a problem.
capacitive touch screen like the iphone and most phones resistive touch screen like some nokia touch mobiles capacitive is much better and smoother
Resistive touchscreens are better if you do not wish to use a stylus. When a stylus is used, capacitive touchscreens respond better. The decision on which is better comes from the applications being used and the preferences of the user.
It can be any type viz. Resistive, Capacitive, Surface acoustic wave. But there are many sub category of above technology.
Some do, the main one being the HTC Flyer. There is recent technology buy Samsung which is a small stylus that works on capacititive touch screens. Pretty much anything works on a resistive touch screen. But yes, anything that has a resistive touch screen usually come with a stylus. With capacitive touch screen tablets, no they do not have styluses.
It's believed that the first ever touch screen was invented in 1965 by a man named E.A. Johnson in Malvern, United Kingdom. The device was a tablet with a capacitive touch screen. The resistive touch screen was created in 1970.
In fact, the capacitive touch screen has a capacitive system. It is built with a layer that holds an electrical charge right on top of the glass panel. When a finger touches the screen, some of the charge escapes into the finger. The decrease in charge is measured in circuits which are usually located at the corners of the screen. And from the relative change in charge at each corner the computer can calculate what the point of contact was with the finger that released some of the charge. http://www.dinodirect.com/Cell-Phones/Cell-Phone-Accessories
The touch screen on a Garmin works by responding to pressure that is appllied to the screen.
No, it doesn't require one due to the capacitive touch screen which is very sensitive like the iPhone's.
The Cobalt SP500 White 5 Capacitive Touch Screen Android 4.0 cell phone appears to be a quality phone. It boasts an impressive 4-5 hour battery life, built in Wi-Fi and a high resolution display screen.
